<h2><u>Density</u></h2>
Problem:
a solid is 5 cm tall 3 cm wide and 2 cm stick it has a mass of 129 g what is its density
Answer:
Solution:
To achieve a volume of 30, multiply 5,3, and 2 together. Density is defined as the ratio of mass to volume, thus divide 129 by 30. You'd obtain a mass of 4.3.
- Therefore 4.3 g/cm³ would be the answer.
